{"version":"1.0","type":"rich","title":"A7 Line","description":"This line chart, created with D3, visualizes the trend of smoking prevalence (as a percentage of total population) from 1980 onward across several Asian countries and the World. The x-axis encodes time using a time scale, while the y-axis maps the percentage of smokers. Each line represents a country, distinguished by color via an ordinal scale, with a legend included. The visualization uses a cleaned dataset from the CSV, filtering for countries like China, India, Pakistan, Sri Lanka, and the World, to compare smoking trends. The chart includes labeled axes, a title, and a legend, making it easy to compare the trajectories across these regions. The example demonstrates how to build a multi-series line chart with D3.js, including data loading, nested data grouping, scales, axes, and legends. The visualization is rendered in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8d62ef6aa453402fbca5345006ba9d4c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
